MultiSUB Choice Horizontal Gel Tank: Exceptional Versatility and Resolution
The MultiSUB Choice Horizontal Gel Tank is the most versatile system in the Geneflow range, specifically designed to offer a flexible solution for laboratories with changing research needs. By offering a platform that supports three distinct tray lengths—15 x 7cm, 15 x 10cm, and 15 x 15cm—this unit allows researchers to select the optimal gel length for their specific application at the time of purchase, or upgrade later without buying a new tank. Ideally suited for restriction fragment analysis, sample preparation, or checking high numbers of samples, the MultiSUB Choice is a workhorse for modern molecular biology.
For applications requiring extended separation distances, the MultiSUB Choice Stretch systems expand this versatility further with 15 x 20cm and 15 x 25cm tray options. This increased run length allows for high-resolution separation of complex bands and accommodates significantly higher sample throughput—up to 350 samples per gel. Despite this high capacity, the units are engineered to maintain low buffer volumes, ensuring economical operation without compromising resolution. Speed loading is facilitated through a wide range of multi-channel pipette compatible combs, streamlining the workflow for high-throughput screening.
Key Benefits:
- Exceptional Versatility: Multiple tray options. The standard unit supports 7, 10, and 15cm gel lengths, while Stretch units accommodate up to 25cm for maximum flexibility.
- High Throughput Capacity: Run up to 350 samples. Maximising comb and tray options allows for 210 samples on standard units and up to 350 samples on Stretch 25 models.
- Optimised Resolution: Clear band separation. The 15cm and stretch run lengths allow restriction fragments or close molecular weight sample bands to be easily separated and identified.
- Speed Loading: Multi-channel compatible. A wide range of combs (10, 14, 16, 18, 28, and 30 sample) are compatible with multi-channel pipettes to reduce loading time.
- Economical Design: Low buffer consumption. The compact tank design requires only 500ml of buffer for standard units and 1000ml for stretch units, reducing reagent costs.
